ORNAlVI EN-TAL M ETAL PLATE.

SPECIFICATION forming part of Letters Patent No. 458,448, dated August25, 1891.

Application filed April 28, 1891.

To all whom it may concern:

Be it known that I, EDWIN C. EWING, of YVheeling, in the county of Ohioand State of WestVirg-inia, have invented a new and use ful Improvementin Ornamental Metal Plates, of which the following is a full, clear, andexact description.

My invention relates to an improvement in ornamental metal platesdesigned for use in the construction of ornamental ceilings, walls,wainscoting, &c., and it is illustrated in the accompanying drawings, inwhich Figure 1 shows in plan view three of my improved metal platesjoined together. Fig. 2 is a vertical section on the line II II of Fig.1, and Fig. 3 is a perspective view of one of the metal plates.

Like symbols of reference indicate like parts in each.

My improved metal plate consists of a piece of sheet metal 2 of suitableoutline, whose edges are turned inwardly at right angles to form flanges3, and are provided at suitableintervals with horizontally-projectingtongues 4, differently placed on opposite sides, so that two adjacentplates may be interlocked by means of said tongues, as shown in Figs. 1and 2.

In the drawings the plates are illustrated as of quadrilateral form; butit should be understood that they may be made of other suitable outline.

Serial No. 390,747. (No model.)

In setting the plates in position they are placed side by side or end toend, so that the locking-tongues on one shall fit under the edges of theflanges 3 of the next adjacent plate, as shown in Fig. 1. The metalplates may thus be held together and may be con fined to the surfaceagainst which they are placed, either by suitable securing devicesplaced at the margins of the series, or when the nature of the surfaceagainst which they are applied will admit they may be secured by nailsor tacks driven through the tongues.

My improved metal plate may be modified in form and in ornamentation inmany ways by the skilled-constructor within the scope of the claims.

What I claim, and desire to secure by Letters Patent, is

.1. Asancw article of manufacture, asheet-v metal plate having laterallockingtongues, l,

substantially as and for the purposes def scribed. 2. As a new articleof manufacture, a sheetmetal plate having marginal flanges 3 andlocking-tongues 4 projecting therefrom, substantially as and for thepurposes described. In testimony whereof I have hereunto set my handthis 25th day of April, A. D. 1891. EDIVIN O. EWING. Witnesses:
